Abstract
Today, wide rational sources have been offered by current research on ethylene gas and related sources, for explaining influence of applied (exogenously) chemicals including different plant growth regulators (PGRs). In this respected, it is described widely that ethephon encourages ripening process and increases level of ethylene in plant cells which promote usual ripening processes in fruits and may influence storage fruit quality and adjourn harvesting process. Ministry of Agriculture has explained that various fruits when subjected to exogenously ethylene at lower concentration stimulate ripening activity and declared as safe (ranging from 0.001-0.01%) for human consumption. Exogenous application of various chemicals expressively declined disease incidence especially post-harvest, consequently increased fruitquality including shelf life of the fruit. Among these chemicals, the ethrel has been recognized for better results. It is established that pre and post treatment with various chemicals to bearing trees and fruits may lead to useful results. But in both cases, results may vary. From collected literature It is reviewed that these ripening substance influence harvesting process, date and monetary revenue generated by a grower by making effective selling strategy.
